Mouse Detection

I'm guessing this is kind of a long shot, judging by how limited the standard W3 World Editor is for this sort of thing, but here goes:

Does anyone know of a way to detect when a mouse button is hit?

Or, even better, does anyone know of a way to detect how long a mouse button is held down??

Are there any other versions of the world editor that would make this easier?

It is easy as hell to detect a right mouse click. You only need a unit and then detect any "smart" orders given to it

It is impossible to detect how long a mouse button is held down.

Left clicks require trackables which btw suck.

1)Detecting Mouse clicks (left) on any units is possible- Map example GhostCity (protected).

Based on selection triggers.

But what about detecting left mouse button clicks on empty terrain?

Like Vex said, trackables. But unless I am mistaken there are some major issues with detecting who clicked. And you must create all the trackables, which may lead to some lag. I think someone once said that it causes some lag when you have lots of them around.

The problem with trackables is, they were never really finished, so they lack a bunch of functionality. You can't even destroy them.

But they *can* work, in multiplayer as well. It's just too much trouble for anyone to have actually used them so far.

If trackables suck selection events are the spawn from hell.

That Click detection method has awful delay issues plus other issues you note as an user
